      NATURE
AND SCOPE OF GUARANTY

       

      Section
1.1                                  Guaranty of
Debt.  Each Guarantor hereby irrevocably, unconditionally, and
jointly and severally guarantees for the ratable benefit1 of each Lender the prompt payment of each such
Lender's Pro Rata Share of the Guaranteed Obligations, which shall be
immediately due and payable upon demand after the occurrence of any default or
event of default under any of the Documents.

       

      Section
1.2                                  Nature of
Guaranty.  This Guaranty is an irrevocable, absolute,
continuing guaranty of payment and performance and not a guaranty of
collection.  The obligations of each Guarantor to the Lenders under
this Guaranty shall be joint and several.  This Guaranty shall not be
discharged by the assignment or negotiation of all or part of the
Notes.

       

      Section
1.3                                  Guaranteed Obligations Not
Reduced by Offset.  The Guaranty and obligations of the
Guarantors to the Lenders shall not be reduced, discharged or released because
or by reason of any existing or future offset, claim or defense of EBOF or any
of its Subsidiaries, or any other party, against the Lenders.

       

      

        

      

        
        1           The
ratable benefit will be determined by calculating the Lender's pro rata share
("Pro Rata
Share"), which means the ratio determined by dividing (x) the face amount
of the Notes then held by such Lender by (y) the face amount of Notes then held
by all Lenders.

         

      


      
        
           


        

        
           


          
            

          

        

        
           


        

      


      Section
1.4                                  Payment By
Guarantor.  If all or any part of the obligations under this
Guaranty shall not be punctually paid when due, the Guarantors shall,
immediately upon demand by the Lenders pay in lawful money of the United States
of America, the amounts due to the Lenders at the addresses as set forth herein
for the Lenders.  Such demand shall be deemed made, given and received
in accordance with the notice provisions hereof.

       

      Section
1.5                                  No Duty To Pursue
Others.  It shall not be necessary for the Lenders (and the
Guarantors hereby waive any rights that the Guarantors may have to require the
Lenders), in order to enforce the obligations of the Guarantors hereunder, first
to (a) institute suit or exhaust its remedies against EBOF or any Subsidiary or
others liable under any of the Documents, or any other person, (b) enforce the
Lenders' rights against any collateral which shall ever have been given to
secure any of the obligations of EBOF or its Subsidiaries, (c) enforce the
Lenders' rights against any other guarantors, (d) join EBOF or its Subsidiaries
or any others liable on the Guaranteed Obligations in any action seeking to
enforce this Guaranty, or (f) resort to any other means of obtaining payment of
the Guaranteed Obligations.  The Lenders shall not be required to
mitigate damages or take any other action to reduce, collect or enforce the
Guaranteed Obligations.

       

      Section
1.6                                  Payment of
Expenses.  In the event that any Guarantor should breach or
fail to timely perform any provision of this Guaranty, the Guarantors shall,
immediately upon demand by the Lenders, pay the Lenders all reasonable
out-of-pocket costs and expenses (including court costs and attorneys' fees)
incurred by the Lenders in the enforcement hereof or the preservation of the
Lenders' rights hereunder.  For the avoidance of doubt, the foregoing
payment obligation shall be a joint and several obligations of the
Guarantors.

       

      Section
1.7                                  Effect of
Bankruptcy.  In the event that, pursuant to any insolvency,
bankruptcy, reorganization, receivership or other debtor relief law, or any
judgment, order or decision thereunder, the Lenders must rescind or restore any
payment, or any part thereof, received by the Lenders in satisfaction of the
obligations hereunder, any prior release or discharge from the terms of this
Guaranty given to Guarantors by the Lenders shall be without effect, and this
Guaranty shall remain in full force and effect.  It is the intention
of the Guarantors that the Guarantors' obligations hereunder shall not be
discharged except by the Guarantors' indefeasible payment of such obligations
and then only to the extent of such performance.

       

      Section
1.8                                  Waiver of Subrogation,
Reimbursement and Contribution.  Notwithstanding anything to
the contrary contained in this Guaranty, each Guarantor hereby unconditionally
and irrevocably waives, releases and abrogates any and all rights it may now or
hereafter have under any agreement, at law or in equity (including, without
limitation, any law subrogating the Guarantor to the rights of the Lenders), to
assert any claim against or seek contribution, indemnification or any other form
of reimbursement from EBOF, its Subsidiaries, or any other party liable for
payment of any or all of the Guaranteed Obligations for any payment made by any
Guarantor under or in connection with this Guaranty or otherwise.

      REPRESENTATIONS
AND WARRANTIES

       

      To induce

warrants to the Lenders as follows:

       

      Section
3.1                                  Benefit.  EBOF
is the direct or indirect owner of interests in each Guarantor (as the case may
be), and each Guarantor has received, or will receive, direct and indirect
benefits from the making of this Guaranty.

       

      Section
3.2                                  Familiarity and
Reliance.  Each Guarantor is familiar with, and has
independently reviewed books and records regarding, the financial condition of
EBOF and its Subsidiaries; however, no Guarantor is relying on such financial
condition as an inducement to enter into this Guaranty.

       

      Section
3.3                                  No Representation By
Lenders.  None of the Lenders, or any other party has made any
representation, warranty or statement to any Guarantor in order to induce a
Guarantor to execute this Guaranty.

       

      Section

Condition.  As of the date hereof, and after giving effect to
this Guaranty and the contingent obligation evidenced hereby, each Guarantor is,
and will be, solvent, and has and will have assets which, fairly valued, exceed
its obligations, liabilities (including contingent liabilities) and debts, and
has and will have property and assets sufficient to satisfy and repay all of its
obligations and liabilities.

       

      Section
3.5                                  Legality.  The
execution, delivery and performance by each Guarantor of this Guaranty and the
consummation of the transactions contemplated hereunder do not, and will not,
contravene or conflict with any law, statute or regulation whatsoever to which
such Guarantor is subject or constitute a default (or an event which with notice
or lapse of time or both would constitute a default) under, or result in the
breach of, any indenture, mortgage, deed of trust, charge, lien, or any
contract, agreement or other instrument to which such Guarantor is a party or
which may be applicable to such Guarantor.  This Guaranty is a legal
and binding obligation of each Guarantor and is enforceable in accordance with
its terms, except as limited by bankruptcy, insolvency or other laws of general
application relating to the enforcement of creditors' rights.

      Section
4.1                                  Effective
Date.  This Guaranty shall be placed into escrow pursuant to an
escrow agreement (the form of which is attached hereto as Exhibit B) and shall
be released from escrow and become effective as of the Dismissal
Date.

       

      Section
4.2                                  Limitation of
Liability.  Each Guarantor hereby confirms that it intends that
its obligations under this Guaranty will not constitute fraudulent transfers or
conveyances under the Bankruptcy Code, the Uniform Fraudulent Conveyance Act,
the Uniform Fraudulent Transfer Act, or any similar foreign, federal, or state
law.  To the extent necessary to effectuate the foregoing intention,
each Guarantor irrevocably agrees that its obligations under this Guaranty at
any time shall be limited to the maximum amount as will result in such
obligations not constituting a fraudulent transfer or conveyance under such
foreign, federal, or state law.

       

      Section
4.3                                  Other Contractual
Obligations.  To the extent that any provision of this Guaranty
results in an event of default under any agreement entered between any Guarantor
and a third party before the effective date of this Guaranty, such provision of
this Guaranty shall become null and void only to the extent such provision
results in the event of default.

       

      Section
4.4                                  Waiver.  No
failure to exercise, and no delay in exercising, on the part of the Collateral
Agent or Lenders, any right hereunder shall operate as a waiver thereof, nor
shall any single or partial exercise thereof preclude any other or further
exercise thereof or the exercise of any other right.  The rights of
the Lenders hereunder shall be in addition to all other rights provided by
law.  No modification or waiver of any provision of this Guaranty, nor
consent to departure therefrom, shall be effective unless in writing and no such
consent or waiver shall extend beyond the particular case and purpose
involved.  No notice or demand given in any case shall constitute a
waiver of the right to take other action in the same, similar or other instances
without such notice or demand.

      Section
4.5                                  Governing Law, Jurisdiction,
Jury Trial.  All questions concerning the construction,
validity, enforcement and interpretation of this Guaranty shall be governed by
the internal laws of the State of New York, without giving effect to any choice
of law or conflict of law provision or rule (whether of the State of New York or
any other jurisdictions) that would cause the application of the laws of any
jurisdiction other than the State of New York.  Each Guarantor hereby
irrevocably submits to the exclusive jurisdiction of the state and federal
courts sitting in The City of New York, Borough of Manhattan, for the
adjudication of any dispute hereunder or in connection herewith or with any
transaction contemplated hereby or discussed herein, and hereby irrevocably
waives, and agrees not to assert in any suit, action or proceeding, any claim
that it is not personally subject to the jurisdiction of any such court, that
such suit, action or proceeding is brought in an inconvenient forum or that the
venue of such suit, action or proceeding is improper.  Each Guarantor
hereby irrevocably waives personal service of process and consents to process
being served in any such suit, action or proceeding by mailing a copy thereof to
such party at the address for such notices to it under this Guaranty and agrees
that such service shall constitute good and sufficient service of process and
notice thereof.  Nothing contained herein shall be deemed to limit in
any way any right to serve process in any manner permitted by
law.  EACH GUARANTOR
HEREBY IRREVOCABLY WAIVES ANY RIGHT IT MAY HAVE, AND AGREES NOT TO REQUEST, A
JURY TRIAL FOR THE ADJUDICATION OF ANY DISPUTE HEREUNDER OR IN CONNECTION WITH
OR ARISING OUT OF THIS GUARANTY OR ANY TRANSACTION CONTEMPLATED
HEREBY.

       

      Section
4.6                                  Amendments.  This
Guaranty may be amended only by an instrument in writing executed by either the
party or an authorized representative of the party against whom such amendment
is sought to be enforced, or by the holders of a majority of the then
outstanding principal amount of the 2008 Amendment Notes.

       

      Section
4.7                                  Parties Bound; Assignment;
Joint and Several.  This Guaranty shall be binding upon and
inure to the benefit of the parties hereto and their respective successors,
assigns and legal representatives; provided, however, that no
Guarantor may, without the prior written consent of the Lenders, assign any of
its rights, powers, duties or obligations hereunder.

       

      Section
4.8                                  Headings.  Section
headings are for convenience of reference only and shall in no way affect the
interpretation of this Guaranty.

       

      Section
4.9                                  Recitals.  The
recital and introductory paragraphs hereof are a part hereof, form a basis for
this Guaranty and shall be considered prima facie evidence of the facts and
documents referred to therein.

       

      Section
4.10                                  Rights and
Remedies.  The exercise by the Lenders of any right or remedy
hereunder or under any other instrument, or at law or in equity, shall not
preclude the concurrent or subsequent exercise of any other right or
remedy.

       

      Section
4.11                                  Intentionally
Omitted.

       


      
        
           


        

        
           


          
            

          

        

        
           


        

      


      Section
4.12                                  Extensions of Deadlines and
Notice of Trigger Events.  Any deadline under this Guaranty may
be extended by the mutual written agreement of the Lenders and EBOF (on behalf
of the Guarantors).  In the event of any default under this Guaranty,
the defaulting party shall be entitled to three (3) business days' notice of the
default and the opportunity to cure such default.

       

      Section
4.13                                  Recovery by
Lenders.  Any proceeds recovered by any Lender under this
Guaranty in excess of its Pro Rata Share of the Guaranteed Obligations shall be
held by such Lender in trust for the pro rata benefit of the other Lenders and
distributed accordingly.  This provision shall survive termination of
this Guaranty.

       

      Section
4.14                                  After Acquired
Claims.  In the event that a Lender acquires (and continues to
hold) the Notes and Warrants (the "Excluded Securities")
under the Transaction Document of a Noteholder that is not a signatory hereto
(an "Excluded
Noteholder"), such Excluded Securities acquired (and held) by such Lender
shall be deemed to be Notes and Warrants of such Lender governed by the terms
and conditions of this Guaranty and the Collateral Documents (and the benefits
thereunder) as if such Excluded Securities were held by such Lender as of the
date of this Guaranty (but only for so long as such Excluded Securities are held
by such Lender).  The Pro Rata Share of any Lender that acquires Notes
from an Excluded Noteholder (or that transfers any portion of its Notes) shall
be adjusted accordingly.

       

      Section
4.15                                  Entirety. THIS
GUARANTY EMBODIES THE FINAL AND ENTIRE AGREEMENT OF THE GUARANTORS WITH RESPECT
TO THE GUARANTORS' GUARANTY OF THE GUARANTEED OBLIGATIONS AND SUPERSEDES ANY AND
ALL PRIOR COMMITMENTS, AGREEMENTS, REPRESENTATIONS, AND UNDERSTANDINGS, WHETHER

LENDERS, NO COURSE OF PERFORMANCE, NO TRADE PRACTICES, AND NO EVIDENCE OF PRIOR,
CONTEMPORANEOUS OR SUBSEQUENT ORAL AGREEMENTS OR DISCUSSIONS OR OTHER EXTRINSIC
EVIDENCE OF ANY NATURE SHALL BE USED TO CONTRADICT, VARY, SUPPLEMENT OR MODIFY
ANY TERM OF THIS GUARANTY.  THERE ARE NO ORAL AGREEMENTS BETWEEN OR
AMONG THE GUARANTORS AND ANY LENDER.

       

      Section

Novation.  The Guarantors hereby acknowledge and agree that
this Guaranty shall modify, extend, renew and continue the terms and provisions
contained in the Existing Guaranties and shall not extinguish or release the
Guarantors from any liability under such Existing Guaranties or otherwise
constitute a novation of the obligations thereunder.

4.17                                  Reaffirmation.  Each
Grantor (as defined in the Amended and Restated Security Agreement) hereby

Security Agreement are valid and continuing and are and shall remain unimpaired
